Issa determined there is a linear relationship between how far up the hill she starts skiing and the length of her jump starting at 90 ft up the hill how far should she expect to jump?
distance jump
50ft 37ft
65ft 48.1ft
80ft 59.2ft
95ft 70.3ft
110ft 81.4ft
There is exactly a 11.1 ft increase in jump length per 15 ft increase in starting location. The slope is 11.1/15 = 0.74
For 90 ft, add 0.74*10 to the jump value at x = 80.
59.2 + 0.74*10 = 66.6 ft
